The trilobite biostratigraphy for the Balang and “Tsinghsutung” formations, Cambrian Series 2, Stage 4 in the Balang area, Jianhe, Guizhou, South China

Ongoing work is carrying out in the Balang and “Tsinghsutung” formations to aim a suitable candidate for the base of the Cambrian Series 2, Stage 4.

Description
Summary:Ongoing work is carrying out in the Balang and “Tsinghsutung” formations to aim a suitable candidate for the base of the Cambrian Series 2, Stage 4. The revision of the trilobite systematics and zonation shed light about the stratigraphic distribution and the geographical distribution of the new trilobite-based zones in the Balang area (South China). Our results suggest that either Oryctocarella duyunensis or Arthricocephalus chauveaui could be good candidates since they also occur in the Eoaagnostus roddyi-Arthricocephalus chauveaui Zone of the Henson Gletscher Formation, North Greenland. Se está trabajando en las formaciones de Balang y “Tsinghsutung” para encontrar un candidato adecuado para la base de la Serie 2 del Cámbrico, Piso 4. La revisión de la sistemática y zonación bioestratigáfica de los trilobites arroja luz sobre las distribuciones estratigráfica y biogeográfica de las nuevas zonas basadas en trilobites en el área de Balang (China meridional). Nuestros resultados sugieren que tanto Oryctocarella duyunensis como Arthricocephalus chauveaui podrían ser buenos candidatos, ya que también se encuentran en la Zona de Eoaagnostus roddyi-Arthricocephalus chauveaui de la Formación de Henson Gletscher, al norte de Groenlandia.
